A maritime ship anchor standing upright on the ocean floor, leaning at an angle rather than lying flat, its base half buried in sand. Shape from top to bottom: a hollow ring at the top; a straight vertical shank below it; a horizontal crossbar passing through the shank near the top; at the bottom a wide curved arc whose two ends sweep upward and finish in pointed barbs. Material: a random mix of cobblestone, mossy cobblestone, stone bricks, mossy stone bricks and cracked stone bricks. Broken and weathered, with some blocks missing along the edges. Surrounded by sand, seagrass and kelp on the seabed.
